The fitting uses a poly-to-poly insert design and is secured with stainless steel clamps, creating a reliable mechanical connection without solvent cement or heat fusion. Rated to ASTM D-2609 and listed under NSF 14 and NSF 16 for potable water service, this coupling meets recognized standards for water distribution fittings. It is suited for irrigation systems, rural water lines, and similar cold water distribution work where PE pipe is the material of choice.\u003c\/p\u003e\u003cp\u003eThis coupling is intended for cold water service only and is not approved for use with compressed air, gases, or hot water. It is also not approved for installation inside a dwelling. Typical applications include agricultural irrigation, rural water supply lines, and outdoor cold water distribution systems where polyethylene pipe is used. Installation requires stainless steel clamps to secure the insert fitting to the PE pipe. Any modifications made to the fitting void the manufacturer warranty.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReducing insert design connects 1-inch PE pipe to 3\/4-inch PE pipe in a single fitting\u003c\/li\u003e\n\u003cli\u003ePoly-to-poly construction compatible with standard polyethylene insert fitting installation methods\u003c\/li\u003e\n\u003cli\u003eSecured with stainless steel clamps for a durable mechanical connection\u003c\/li\u003e\n\u003cli\u003eASTM D-2609 listed construction standard\u003c\/li\u003e\n\u003cli\u003eNSF 14 and NSF 16 listed for potable cold water service\u003c\/li\u003e\n\u003cli\u003eCold water only — not rated for compressed air, gas, or interior dwelling use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with polyethylene (PE) pipe in cold water distribution applications.

Before beginning work, shut off the water supply and relieve any pressure in the line. Insert the fitting fully into the PE pipe ends and secure each side with appropriately sized stainless steel clamps tightened per clamp manufacturer guidelines. Do not modify the fitting in any way, as modifications void the warranty and may compromise the integrity of the potable water system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Poly Insert x Poly Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyethylene (Poly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService\u003c\/strong\u003e: Cold water only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 20 per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM D-2609\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF 14, NSF 16 (potable water)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TIGRE USA INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1429-131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TIGRE","offers":[{"title":"Default Title","offer_id":51525526847794,"sku":"1429-131","price":23.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e086b50e5d03b82839b65f78f4dbc158_4990986d-77b3-4827-8fee-63b8447e94ca.jpg?v=1785476349","url":"https:\/\/voomisupply.com\/products\/tigre-usa-inc-1429-131-reducing-poly-insert-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
